ill ly-IPING FOR GAS-RANGES.

Specification of Letters E'atent.

Patented Mar. 3, 1914.

/ Application filed March 15, 1912. Serial No. 683,939.

To all whom 'it may concern i Be it known that I, Heiner C. MAUL, a citizen of the United States, residing at Detroit, in the county ofi" lVayne, State ot hilichigan, have invented certain new and n u! u useful` Improvements in Piping for Gas- Ranges; and I do decil/are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which!` it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters ot' reference inarked thereon, which ntorna a part ot this specification.

This invention relates to a system et' piping ifo-r gas ranges, and consists in the con struction and arrangement of parts hereinafter more fully set forth and pointed out particularly in the claims.

The object of the invention is to provide a simple arrangement for so disposing' the inain gas supply pipe as to enable the independent connection thereto of the burners for heating the cooking top, and the burners for heating the oven of a gas range, provision being made for controlling a plurality ot burners troni one gas cock and for readily connecting a plurality ot' cooking ranges in a battery, and facilitating the suliplying ot gas to the several. burners of each range without interfering with the sup ply to the other ranges.

The above object is attained by the arrangement illustrated in the accompanying drawing, in which Figure 1 is an eleva-tion ot two gas ranges piped in accordance with my invention, and connected to show the manner ot' joining a plurality ot ranges. view through the hollow couplings which connect the sections of the main gas pipe and through which gas is supplied to the burners of the range.

Referring to the characters of reference, .l designates a gas range of any suitable type having a cooking top 2. Crossing the front of the range transversely, preferably near the top. is the main gas supply pipe which may be made to supply gas to any number ot ranges desired. Each range is provided With side pipes l and 5 respectively7 which extend vertically on each side of the oven door 6. The side pipe l at its upper end is provided with a horizontally extending portion 7 which crosses a part of the front ot Fig. 2 is a sectionall the range, and which supplies gas to a plurality ot burners 8 extending under the cooking top. The lower end of the side pipe #l is provided with a horizontally extending portion 9 which cross-es a part oi the front ot' the range at the bottoni thereof to supply gas to a plurality ot' oven burners 10. 'lhe side pipes '1- and 5 are connected with the niain supply pipe 3 through vertical couplings 11 in the torni of hollow castings. Each o't the couplings l1 is provided at its upper end with a head 12 into one side oi which the pipe 3 connects. At the oppositr` side ot' said head it is provided with laterally extending flanges 13. Two of theseI heads are connected together by transverse bolts 14; passing through said, flanges to etl'ect a continuity of the supply pipe through said heads, as clearly shown in Fig. l, packing l5 being employedbetween the `faces ot said heads to effect a tight joint. By employing the fittings or couplii'lgs 11 having the heads 12 provision is made for connecting a battery o'f ranges together as shown, and at the salue time affording each range an independent connection with the supply pipe. At the terminal of the supply pipe, as at the left of Fig. 1, the opening through the head 12 oit the fitting 1.1 is closed by a plate 1G secured to the flange 13 of said head by bolts 17, the joint between the plate and head being rendered tight by the interposed packing 18. The lower ends ot the fittings 11 are connected to the side pipes 4t and 5 respectively through the medium ot' T-couplings 19. In each of the side pipes Yt, below the point ot' connection ot' the fittings 1l therewith, is a gas cock 2() which controls the supply otf gas to all et the oven burners 10. Also located in each ot the side pipes l and 5, above the point of connection oi the fittings 11 therewith, is a gas cock 21 which controls the supply of gas to one-half of the burners under the cooking top.

Extending from the lower end oit cach of 'the side pipes 5 is a horizontal section 22 which supplies gas to a pilot burner or lighter t'or the oven burners. ln each of the side pipes 5 is a cock 27 which controls the supply of gas to the lighter 23 of coniinon and well known construction for the oven burners, Extending laterally from the upper end ot each of the side pipes 5 is a pipe section 24 which supplies gas to the remainder of the burners 8 under the cookn ing top. Communicating .centrally with each of the sections of the supply pipe 3 on each range is a gas cock 25 which controls the supply of gas to a pilot burner or lighter 26 for the burners under the top of the range.

It will be noted on referring to the left of Fig. l, at the bottom, that the endsof the pipes 9 and 22 are closed by caps 28. To connect said closed pipe ends and prevent the end of pipe 9 being bent down- 'waldly by any weightplaced thereon the embracing sleeve 29 is employed, as shown at the right of Fig. l.

The elbows at the lower ends of the side pipes 4L and 5 are embraced by brackets 30, mounted on the bases of the ranges, which firmly hold said pipes in place. The hinge straps 3l of the oven doors 6 are provided with eyes which are mounted to turn upon the lower pipe sections 9 and 22.

It will be noted that the horizontal sections 7 and 24 extending inwardly from the upper ends of the side pipes 4l and 5 respectively, each supplies gas to one-half of the burners under the cooking top. By this arrangementl one-half of said burners may be controlled by either of the gas cocks 2l, enabling either side of the top to be heated, or both sides, as may be desired. It will further be noted that the oven burners may be controlled entirely independently of the burners under the cooking top; that all of the oven burners may be supplied with gas by opening the gas cock Q0, and the supply of gas to said burners cut off -by closing` said cock. p

The arrangement herein shown provides for simultaneously supplying gas to all of the oven burners and to all of the burners under the cooking top without interference. Attention is called to the fact that by reason cf the arrangement shown the connection of a. battery of gas ranges to a source of gas supply is greatly facilitated, and that other ranges may be readily added to the battery from time to time as desired.

By connecting` the sections of the supply pipe together by the fittings as shown, a battery of gas ranges may be supplied with gas in such a manner as to enable any one of the units to be removed without disturbing the other units of said battery.

Having thus fully set forth my invention, what I claiinV as new and desire to secure by Letters Patent, is:-

l. A gas range having a series of burners under its cooking top and a series of burners under the bottom of its oven, a horizone tal main feed pipe, an auxiliary top feed pipe supplying the topxy burners, an auxiliary botto-m feed pipe supplying the oven burners, a vertical supply pipe connecting said auxiliary pipes, and a fitting connecting the main supply pipe with the Vertical supply pipe at a point between said auxiliary pipes.

Q. In a gas range, a horizontal feed pipe coextensive wit-h said range, a fitting at each end of said pipe for effecting a clo-` sure thereof or connection with the succee-ding pipe section, burners for said range, auxiliary feed pipes communicating with said burners and connected with each of said fittings respectively.

In testimony whereof, I sign this specification in the presence of two witnesses.
